Three new aflatoxigenic species of Aspergillus section Flavi isolated in Portugal
Soares, Célia; Peterson, Stephen; Rodrigues, Paula; Lima, Nelson; Venâncio, ArmandoThree new aflatoxin-producing species isolated from two Portuguese commodities, almonds and maize, are described. A polyphasic approach based on phenotypic (morphology and extrolites) and molecular characterizations was used to identify these isolates as belonging to new species. From the study of the twenty two isolates obtained in maize and almonds, two were identified as Aspergillus flavus, six as A. minisc...
Multilocus sequence identification of penicillium species in cork bark during p...
Serra, Rita; Peterson, Stephen W.; Centro Tecnológico da Cortiça; Venâncio, ArmandoDespite several studies reporting Penicillium as one of the most frequent fungal genera in cork planks, the isolates were rarely identified to species level.We conducted a detailed study to identify Penicillium species from the field to the factory environment prior to and after boiling the cork planks. A total of 84 samples were analyzed. Of the 486 Penicillium isolates phenotypically identified, 32 representa...
Penicillium astrolabium and penicillium neocrassum, two new species isolated fr...
Serra, Rita; Peterson, Stephen W.We describe two new terverticillate Penicillium species isolated from grapes on the basis of phenotypic and phylogenetic differences from known species. The strains were isolated in the course of a study to establish the mycobiota of grapes in Portugal. Penicillium astrolabium is phenotypically similar to P. olsonii but differs from it by two cultural characters, growth rates and the colony reverse color. P. ne...
